File Not Found During Patch Install

I used the latest version of SWAssistant (2.85)to attempt an install a patch bundle from ITRC. I get "file not found" during the install process. I checked patches in my temporary depot, and the patches are missing files. Example is the following. My OS is 11.11.

"/tmp/mydepot/PHKL_36578/C-INC/usr/include/sys/pstat/pset_pstat_body.h" to copy it. No such file or directory (2).
